2018 Mercedes-Benz A-Class 1.5L Diesel · WH11 ABY

The defining mechanical story of this 2018 A-Class is one of largely consistent roadworthiness, punctuated by a single tyre-related failure and a recurring theme of tyre wear and sidewall damage across the recorded tests. The most recent examination on 2 September 2025 returned a clean pass with no advisories, mirroring the 2023 pass and confirming that the vehicle has generally cleared the test without defect entries. The single failure on 28 September 2024 was a major defect for a nearside rear tyre with a cut exposing ply or cords, and the vehicle passed a re-test the same day, indicating the issue was rectified on site. Prior to that, the 2022 test recorded three advisories, all centred on the tyres: both fronts worn close to the legal limit with edge wear, and outer sidewall scuffing on the nearside front and nearside rear. With three consecutive tests from 2023 onwards returning either a clean pass or a single repaired tyre issue, the trend appears stable rather than deteriorating, although the tyres remain the only component group with any recorded history. Against an age of approximately eight years, the recorded mileage of 63,151 equates to an annual accumulation of around 7,894 miles, which sits broadly within typical parameters for a privately used vehicle of this vintage. There are no extended gaps in the testing history that would suggest a prolonged period off the road, with annual or near-annual tests recorded from 2022 through 2025. Mileage progression between tests is consistent with steady, moderate use rather than the rapid accumulation that accelerates wear on clutches, dual-mass flywheels, diesel particulate filters, or suspension components. Equally, the figure is not low enough to raise concerns about dried seals, stale fluids, or seized brake calipers from extended standing. In practical terms, the usage profile suggests components such as brake discs, pads, and suspension bushes have been exercised regularly and are unlikely to have suffered the accelerated degradation associated with high annual mileages. Given the tyre-related history, a prospective buyer should pay particular attention to the remaining tread depth across all four corners and inspect each sidewall closely for any scuffing, cracking, perishing, or cuts, particularly on the nearside rear where the 2024 failure originated and where 2022 advisory sidewall damage was noted. Edge wear on both fronts in 2022 suggests checking current alignment settings and feeling for steering pull or uneven tyre wear during a test drive, as persistent edge wear can indicate worn suspension bushes, droop links, or tracking issues rather than simple rotation habits. The 2022 advisory regarding undertrays obscuring components is also worth noting; on inspection, request that any fitted covers be removed so the underside, including subframe mounting points, suspension arms, and anti-roll bar linkages, can be visually examined for corrosion or oil weeping. Listen for clonks or knocking from the front suspension over speed humps and uneven surfaces, as worn bushes or top mounts are common on A-Class vehicles of this age and would not necessarily have been flagged if within tolerance at the time of test. Beyond the recorded items, a physical inspection should include a thorough check of the brake system for binding calipers, uneven pad wear, and disc lipping, given the vehicle's age and the fact that no brake-related advisories have been recorded to date. Examine the exhaust system for any corrosion at mounting brackets and joints, and inspect under the bonnet for oil misting around the cam cover or turbo area, which is a known concern on Mercedes petrol engines of this era. Finally, verify that the tyre failure from September 2024 was properly rectified by checking for a matching replacement tyre on the nearside rear, and confirm that the wheel itself was not damaged, as a deep cut reaching the ply can occasionally be accompanied by rim scuffing that affects balancing and long-term tyre wear.
